In the first place, danny, for two years you're wrong by default. Leaving the EU requires triggering Article 50 of the Lisbon Treaty which implies a two-year period of negotiations, only at the end of which does the treaty cease to apply.
Then, after that, like any other country we would deal with the EU as a bloc (eg TTIP with the US, the pending Canada-EU deal, deals between the EU and certain African nations, etc.). And meanwhile other European non-EU countries, such as Norway, still accept some amount of rules as part of their deals with the EU. What deal we get may be similar, or radically different, but at any rate it's completely dishonest to pretend that Brexit guarantees zero EU influence on the UK from now on. dosset is no more right to insist that we *will* have to accept freedom of movement as you are to imply that we can bypass the EU entirely, starting Friday, after a vote to Leave.
